Ok I just got a new order of brass in from a order I placed. Two questions.
1: is my understanding that 9x19 brass is swappable for 9mm. They look th same height and diameter.

2: there are quite a few that have what looks like a cannelure from a bullet printed into them. Is this ok? Here is a picture of the brass. uploadfromtaptalk1342652131217.jpg
